` To aZZ whom it may concern,.-

Be it known that I, FRIEDRICH BEYER, manufacturer, a subject of theGerman Ernperor, and a resident of Siegmar, near Chemnitz, in theKingdom of Saxony, German Empire, have invented certain new and usefulImprovement-s in Devices for Cutting and Setting Bricks Made byBar-Presses, of which the following is a specification.

My invention relates to a new device for cutting and setting bricksmanufactured by means of the so-called stream-brick cutter.

The advantage of my device lies in the fact I that by means of the samemore than three bricks may be removed at a time, as the bricks cut offon the bar or stream of clay may be automatically separated into groupsof two or three, with sufficient space between them to allow of puttingthe hand between. rlhis is attained by the special construction of thecutting device which is illustrated on the accompanying draWings--vizinFigure 1 in a side view with cutbricks; Fig. 2 in a front view, whereasFig. 3 is a ground plan. Fig. 4 shows how by a shifting of theusualsliding carriage the groups of bricks are separated, whereas Fig. 5shows a section according to line A B of Fig. 4, and Fig. 6 illustratesthe mode of automatically disengaging the mechanism turning the rollers.

Similar letters refer to similar parts throughout the several views. Thenew apparatus arranged on a cutting device of the usual construction has'the special feature that there are arranged frictlon-wheels e and f onthe rollers a and b near the end of the bar or stream of clay d, whichcooperate with a friction-bar fi, arranged on the frame. By shifting thecarriage ZC, supporting the rollers a and b, these rollers are rotatedas their wheels c and f roll upon the bar fi, and thereby somewhat rollaway the two or three cut bricks lying on them. In

` order to give to the first brick a rolling support, the stop-squaremis so arranged that it ma be tilted and is provided with rollers n.

he working of the device is' therefore the following: According towhether four or six bricks are to be cut at a time, four or more wires o(the former is here supposed) are stretched out in the bow p of thecutter. When the bar of clay, which is moved forward in the usualmanner, arrives at the square m, the workman presses down the bow andfour bricks are cut off. Now the carriage 7c is shifted in the usualmanner in the direction of thearrow in Fig. 4. By this shifting isproduced the gap the same as with the usual process. By the shifting ofthe carriage cand the rollers a and b .the wheels e andf roll upon thebari and through the rotation of the rollers resulting therefrom thefirst two bricks are moved forward a little, pushing thereby the sto-square m into 'its horizontal position, and t e first brickis placeduponv the said stop-square m, as shown in Fig. 4. A second gap y isthereby roduced, and the cut bricks are thus divided into two sectionsand can be taken off simultaneously by two removers. In this way it ispossible to remove with this cutting device double the number of bricksattalned by other systems. As the advancing bar or stream of .clay onits touching the rollers a and b meets with resistance, as these rollersare checked intheir rotation by their frictionwheels resting against thebar i, the driving mechanism ought to be disengaged b hand during thisperiod. In order to avoid this, in the device illustrated on theaccompanyi 0f drawings the mechanism turnin the ro lers is automaticallydisengaged W e the stream of clay passes over the rollers a and b;

but as also during the return of the carriage the rollers are notrequired to rotate they remain also disengaged during this period. Theengaging and drsengaging is effected automaticalI f by the arrangementthat the bar i is pressed against the rollers e f or is separated fromthe same by its own weight.

The rack a', is'driven by a projection s, ar'- ranged at a suitableplace of the frame, and a roller t, oscillatingly suspended by means ofl an arm from the rack 'i in a suitable bending of same. This bending isformed in such a manner that the roller t pushes against its inner edgewhen the carriage is moved in the direction of the arrow in Fi 4,thereby hold-V.. A

ing the roller-arm in vertica direction, so that the roller t projectsbelow the lower edge ofl the rack i; but when the carriage is moved inthe direction of the arrow in Fi 6 no projection of said roller 4occurs, as t e bendin of the rack 'L is wide enou h to allow then a eeyielding of the arm wit the roller t inthe direction of the carriagemovement.

As long as the -stream of clay is being advanced, and thus passes overthe rollers 0l and b, the rollers are not in contact with the bar i, asthe latter, held bythe roller t, which rests on the frame, isintheloweredposition. (Shown in Fig. 1.) The mass of clay can therefore inIOO IOL'

IIO

its advance turn the rollers a, and b, there being no obstacle in theway; but if afterthe cutting-that is to say, after the separation-of acorresponding number of bricks 5 from the mass of clay the carriage ismoved in the direction of the arrow, Fig. 4, for the purpose of formingthe interspaces the projection s on the frame passes under the roller t,and the bari during this time presses irmly 1o against thefriction-wheels e f. The rollers a b are rotated and remove the brickslying on them away from the bricks lying on the nonrotating rollers.When this movement is completed, the rack descends again, being nolonger held by the projection s. If now the carriage is moved back inthe direction of the arrow, Fig. 6,-the roller t rises up to theprojection s; but it cannot raise the bar i, as it does no longerproject below the lower edge zo of the bar i, as stated above. Thecarriage therefore goes back without the rollers a b being infiuenced bythe bar fi.

Having now particularly described and ascertained the nature of my saidinvention and 2 5 in what manner the same is to be performed,

I declare that what I lclaim is-.-

1. A device for cutting and setting bricks made by a bar-press,comprising in combination rollers at the end of the bar of clay being 3oprovided with means adapted to move the bricks forward in groups withgaps between the end of the clay-bar and after every group @l #ij/f,/f/IM, A?, @ma @Lfd/AQ of two or more bricks said means consistin ofwheels e, f connected to the rollers a, and adapted to cooperate with abar'iitted on the frame of the press, substantially as described andshown and for the purpose set forth.

2. A device for cutting and setting bricks made by a bar-press, comrising in combination rollers at the end of t ebar of claybeing providedwith means adapted to move the bricks forward in groups With gapsbetween the end of the clay-bar and after every group of two or morebricks, said means conslstin of wheels e, f connected to the rollers a,b and adapted to coperate with a bari fitted on the frame of the press,said bar 'i beingprovided with means which press it against thedrivingwheels e and f by a projection s on the frame,

when the carriage separates the bricks fromA the mass of clay, whilesaid means remove. the bar i from the driving-wheels as long as thecarriage moves backward and the mass of Aclay 1s being advanced,substantially as described .and shown and for the purpose set forth.

In witness whereof I have hereunto signed my name, this 25th .day ofJanuary, 1904, in the presence of two subscribing witnesses.
